Features & specifications

– Trunnion-mounted design: The ball is anchored by trunnions at the top and bottom, providing support and stability even in high-pressure applications.
– Low operating torque: Requires less effort to operate, reducing actuator wear and ensuring smoother performance in high-pressure environments.
– Bi-directional sealing: Spring-loaded seats ensure tight sealing from both directions, independent of flow pressure.
– Anti-blowout stem: Ensures safety and reliability during operation, even in extreme conditions.
– Full bore design: Offers an unobstructed flow path, reducing pressure drop and allowing for smooth operation.
– Corrosion-resistant materials: Built to withstand harsh environments, including H₂S service, with material options for all classes from AA to HH.

Sizes:

Available in sizes from 2 1/16” to 4 1/16”.

Pressure Ratings:

Suitable for pressure ratings ranging from 2,000 PSI to 10,000 PSI, depending on the specific application and configuration.

Temperature Ratings:

Available with API temperature classes from L (-50°F) to U (250°F), making these valves suitable for a wide range of operational environments.

Connection Types:

– Flanged
– Threaded
– Quick Union 1502

Applications:

– Oil and gas pipelines: Ideal for upstream and downstream oil and gas operations, including critical shutoff and flow control in high-pressure systems.
– Subsea operations: Suitable for subsea installations where reliability and durability are essential.
– Refineries and processing plants: Used in applications where high pressure and a reliable seal are required for safety and efficiency.

Materials:

Available in a wide range of materials, including carbon steel, stainless steel, and materials compliant with NACE MR0175 for sour gas service.
